In this mission, your squad runs into an injured Aiello near Hill 493. Fully stock your ammo using the box on the right and then charge up. An artillery barrage begins almost immediately. Run up the right side of the area, but remain behind cover of the trees and rocks.
Clear the nearby enemies, then sprint from one rock to the next one until you locate the machine gunners at the top of the next ridge.
Take Out the Machine Gunners
Move up the right side of the area until you get a clear shot on the three machine gunners. If you are having trouble locating them, use the Objective button to highlight them on-screen.
When the three gunners go down, your squad will make a strong advance on the remaining enemies on the ground. Hang back in cover and pick off the Germans, but let your squad mates take the brunt of the fire. When the path becomes littered with Nazi corpses, Turner sprints up to meet the squad.
Objective: Escort the Engineer
Turner stops next to an engineer armed with a pole charge demolition kit. When you’re ready, make Parker charge up to a rock to find cover. Stay behind and take aim at the machine gunner nest. Keep firing until the machine gun is suppressed, then run over and press the Activate button when next to Parker again.
Suppressive Fire!
If you can keep Private Parker alive through this sequence, you will earn this achievement/trophy.
Once again, stay behind cover and, as soon as the machine gun starts up again, unleash rapid fire. Remember that your shots don’t need to be very accurate to suppress the gun. Sprint up and press the Activate button next to Parker a third time.
Stay where Parker was standing and focus on killing the German infantry who attack from the left side of the bunker. These guys will take out Parker if you order him to move before killing them.
When the German infantry is history, suppress the gun again and sprint up to Parker. He eventually reaches a large rock. You just need to suppress the gun one more time to complete this section of the mission. Although the charge is set, it detonates early and the result isn’t good. Press the Jump button to mantle into the bunker and capture the hill.
